Abstract
A measurement circuit in a motor circuit generates signals for use in a motor control strategy for an electric motor. The measurement circuit comprises a first current sensing means which produces an output signal indicative of the current flowing in a di/dt path connecting the phases of the motor to a ground or a common positive supply voltage, and further comprises a second current sensing means which produces an output signal indicative of the rate of change of current flowing in the ground line, and in which the second current sensing means comprises a Rogowski coil.
